I like the points about using php for logic instead of mysql, I've been doing that for years because I prefer to always do the heavy lifting in php which I know better than SQL.<p>I always felt it was against best practices though, but now I won't worry about it so much.
While interesting, if you haven't read the original article, most of the points lose their meaning.<p><a href="http://blogs.sitepoint.com/2010/11/19/mysql-mistakes-php-developers/" rel="nofollow">http://blogs.sitepoint.com/2010/11/19/mysql-mistakes-php-dev...</a><p>Also, aren't most PHPers using frameworks (like CakePHP or Symphony) now instead of raw-coding PHP? I can imagine this being useful for dealing with small or legacy systems, but I haven't had to write a raw SQL statement in almost a year now.
